I have my Nokia5110 display hooked up on SPI2, with CE on C5, DC on C4, and RST on A3.
I'm doing a bunch of stuff with it, and everything is working great - until I do an analogWrite() to A8.
After that, when I call g.flip(), the screen display scrambles and the LCD needs to be powercycled.
It doesn't seem to happen with any other PWM pins... (I tried the C's right near it, and the A's and B's in the middle)... but A8 does it reliably. Usually I see pieces of the image, but in the wrong place on the screen, but I've also seen it simply blank the LCD as well.
Any thoughts? I can easily work around it, but I figure it's symptomatic of a deeper issue...
